This research proposes a method that aims to evaluate the risk levels of websites based on exposure risks of privacy information. The proposed method considers two aspects as follows. First, we define the risk levels of each privacy information according to its own inherent risk. Second, we calculate the visiting probability of a webpage to measure the expected of the actual exposure of privacy information on that webpage. In this research, we implemented an system to prove that automatically collects websites and calculates their risk levels. For the experiments, we used a real world dataset consisting of a total of websites for 4 categories such as university, bank, central government agency, and education. The experiment results show that the websites in the bank category are relatively well managed, while the others are needed to cope with the exposure of privacy information. Finally, the proposed method in this research is expected to be further utilized in establishing a priority-based approach to alleviate of the privacy information exposure problems.

By using the Korean demographic data and the modified relative risk projection model given in the Committee on the Biological Effect of Ionizing Radiation (BEIR) report-V under the U.S. National Academy of Science, the radiogenic excess risk in Korean population has been evaluated. On the basis of this risk, a safety goal for the safe operation of domestic nuclear power plants has been further derived in terms of personal dose. The baseline risk of death due to all causes in Korea and the trivial risk level, which the society considers safe, were estimated to be $5.2{\times}10^{-3}$ and $5.2{\times}10^{-6}$, respectively. The radiogenic excess cancer risk in Korea has been estimated to be $5.2{\times}10^{-3}$ for tie case of acute exposure to 0.1 Gy and $3.7{\times}10^{-3}$ for the case of chronic lifetime exposure to 1.0 mGy/y. On the basis of these risks estimate, the resulting safety goal for one year opeation of a reactor was 0.05 mSv, which is quite identical with the ALARA guideline prescribed by the USNRC in the Appendix I, 10CFR50.

This paper uses a survey data to analyze the age-specific fertility rates, age-specific cumulative fertility rates, and ages of marriage of the five birth cohorts of Korean women born in the 1940s and thereafter. It was found that later cohorts reach their highest age-specific fertility rate at higher ages than earlier cohorts. The age-specific cumulative fertility rates of the 1950s and 1960 cohorts were found to be much lower than those of the immediately preceding cohorts, while those of the 1970s and 1980s cohorts were not different from those of the 1960s cohorts. Women belonging to later cohorts were found to get married at relatively higher ages. The estimation results of the hazard model show that women belonging to later cohorts and those with more schooling have a tendency to get married at higher ages. The effect of the birth cohorts is thought to be due to the economic, social, and cultural changes in Korea during the late 50 years or so. The time interval between a woman‘s marriage and first birth was found not to be affected by either the year of marriage or that of her birth. Also, those who remained employed for some time around their marriage and those with low schooling were found to have a lower first child birth hazard, which implies that married women’s employment status and family income play an important role in their decisions on childbirth.

기업의 재무구조와 인플레이션과의 관계는 세율에 대한 다양한 형태의 가정을 통하여 연구, 분석되어 왔으나, 이 문제를 확실히 해결하지는 못하였다. 근자에 A. Marcus(1983)가 미국의 은행의 재무구조를 대상으로 한 시계열분석 결과에 의하면 명목이자율의 상승이 미국은행의 부채 대비 자본금 비율을 하락시키는 절대적 요인이 되었다고 한다. 본 연구의 목적은 인플레이션과 은행의 부채 대비 자본금 비율의 상관관계, 더욱 나아가서 은행자산의 위험도가 이 상관관계에 미치는 영향을 분석코자 한다. 본고는 은행규제기관(FDIC 등)의 부채비율과 은행자산(포트폴리오)의 위험도에 대한 규제하에서 은행이 부채(예금)와 자본금의 가치를 극대화하고자 하는 모델을 설정하여 기대 인플레이션 수준이 은행의 적정 자본비율과 자산의 위험도와 어떤 관계가 있는가를 밀러의 균형모델(Miller Equilibrium Model)을 원용하여 분석하였다. 밀러의 균형모델하에서는 기업의 재무구조는 기업가치와 무관한 것으로 나타나고 있다. 즉, 부채를 통한 자금조달에 의해 발생되는 한계세금혜택은 균형하에서는 사라진다는 이론이다. 따라서 인플레이션은 적정 재무구조에는 영향을 미치지 못하게 된다. 왜냐하면 인플레이션은 기업의 세후 부채조달비용과 회사채 투자자 수익에 동일한 영향을 미치기 때문이다. 그러나 은행의 경우 일반 기업과는 달리 은행규제기관의 부채비율 및 자산위험도에 대한 규제압력이 소위 암묵적 규제비용으로 작용하여 은행의 적정자본금비율은 부채(예금)를 통한 자금조달의 한계세금혜택과 이에 따른 한계규제바용이 동일하게 되는 경우에 결정된다. 밀러의 단순균형 모델하에서 한계세금혜택이 없는 것과는 달리 은행의 부채조달에 따른 한계규제비용이 존재하는 이유로 균형조건으로 한계세금이익이 존재하게 된다. 이 경우 인플레이션은 예금자의 실질 세후 예금이자를 상승시키는 것 이상으로 은행의 실질 세후 예금이자 지급비용을 하락시키게 되어 은행의 부채비율을 더욱 높이게 되는 원인이 된다. 또한 은행의 부채비율이 인플레이션과 정(正)의 관계에 있다면 은행규제의 강도에 따라 이 상관계수는 은행자산의 위험도와도 역시 정(正)의 관계에 있게 된다. 미국은행을 대상으로 한 회귀분석에서도 그들의 부채(예금)비율이 기대 인플레이션과 정(正)의 상관관계가 있음이 나타났고 그 상관계수는 은행자산의 위험도와 동일 방향으로 움직임이 판명되었다.

The absence of proactive information security management to ensure availability, accessibility and safety of information can bring serious risks to customers as well as to the organization's performance and competitiveness because improper security management undermines business continuity. This study analyzed the maturity of information security which affects the organizational performance. Through the literature reviews, a research model using the organizational performance as the dependent variable, the risk management process maturity and risk assessment process as independent variables and the information security policy indexes as moderate variables was proposed, and an empirical analysis was made on the basis of survey. The results showed that there was a high causal relationship between information security maturity and organizational performance. However, even if the proportions of information security staff ratio and the information security budget ratio increased, information security maturity did not affect organizational performance. It suggests that information security maturity affects organizational performance, but information security regulations have their limitation as being a catalyst to improve organizational performance.

The purpose of forecasting the traffic accident is to reduce the traffic accident. Therefore, the goal of this study is to provide severity of the accident by Forecasting of Probability of Accident. In Korea, accident data are distributed to the public via internet that includes numbers of accident and fatality as well. And crude level of accident severity in accordance with weather information for metropolitan city level are available by weekly. However, It can not reflect personal needs at specific origin of the travel for a certain traveller. This study aims to consider 68 major intersections with precipitation data, and eventually introduces link based accident severity. In estimating the accident severity both dynamic data such as drivers' characteristics, driving conditions and static data such as geometry of road, intersection characteristics are considered. Also, we identifies accident severity according to the accident type - 'vehicle to vehicle,' 'vehicle to person.' Finally, the outcomes of this study suggests taylor-made accident severity information for a specific traveller for a certain route.

The purpose of the study is to investigate the effects of information search for Korean food brand on perceived risk and preference. To achieve this goal, using 10 exemplary restaurants appointed as Korean food brands in Seoul, a questionnaire survey was used to collect data through interview. Using the SPSS 21.0. total 296 responses were analyzed to test the relationship among variables. The findings are as follows. First, information search for Korean food brand showed that all external search, internal search and direct experience had a positive effect on preference. Second, there was no difference between information search for Korean food brand, risk perception and preference according to gender, but there was a significant difference between information search for Korean food brand, risk perception, and preference according to their age. Third, indifference moderated the relationship between external and internal information search and Korean food preference. Fourth, maladjustment moderated the relationship between external information and direct experience for Korean food preference.

Recently, weather information is getting closer to our real life, and it is a very important factor especially in the transportation field. Although the damage caused by the abnormal climate changes around the world has been gradually increased and the correlation between the road risk and the possibility of traffic accidents is very high, the domestic research has been performed at the level of basic research. The Purpose of this study is to develop a risk map for the road hazard forecasting service of weather situation by linking real - time weather information and traffic information based on accident analysis data by weather factors. So, we have developed a collection and analysis about related data, processing, applying prediction models in various weather conditions and a method to provide the road hazard map for national highways and provincial roads on a web map. As a result, the road hazard map proposed in this study can be expected to be useful for road managers and users through online and mobile services in the future. In addition, information that can support safe autonomous driving by continuously archiving and providing a risk map database so as to anticipate and preemptively prepare for the risk due to meteorological factors in the autonomous driving vehicle, which is a key factor of the 4th Industrial Revolution, and this map can be expected to be fully utilized.

NIR(New Inspection Regime, hereinafter NIR) relating to the PSC(Port State Contorl, hereinafter PSC) has implemented in Asia-Pacific region under Tokyo-MOU from last January 2014. The most noticable difference between NIR and existing TF(Target Factor, hereinafter TF) is to evaluate company performance and to conduct PSC with flexible inspection interval on the basis of Ship Risk Profile; High Risk Ship, Standard Risk Ship and Low Risk Ship. Particularly deficiencies related to ISM Code, more than 5 deficiencies and detention record have a serious effect on the evaluation of Ship Risk Profile. Therefore ship and company are requested to ensure proper implementation of Safety Management System for the changed PSC tendency. Also RO(Recognized Organization, hereinafter RO) and Administration respectively should take suitable actions different to previous measures, such as implementation of cooperation and support system between vessel and company, changing subject and object for avoiding Mannerism in SMS audit, strengthening supervision on RO by Administration and establishment of private-public Partnership network.
